Touchscreen Sensitivity - Missed Touches

Anyone having issues with touchscreen sensitivity?  ~10-15% of the time i try to hit a button on the screen nothing happens and I have to try to press it again.  Sometimes I'll have to try multiple times before I get it.  Can the sensitivity be adjusted?  I wasn't able to find anything in any of the settings for it.

I went back to my 830 to compare and that very rarely misses a touch. One thing I noticed that helps on the 830 interface is every button you touch changes the background to let you know its been touched, whereas not everything does on the 1050 - for example the back button on the top left on some of the screens.
